When Eagan police detective Chad Clausen received a report that an Eagan High School teacher may have had an inappropriate relationship with a student, he believed the matter needed a closer look. Clausen opened an investigation into music teacher Brett David Benson in 2022 after the Rosemount-Apple Valley-Eagan district contacted police on a report that Benson, then age 35, allegedly sneaked a student out of her room during a school trip to Italy.
